摘要

•ZnO-ZnAl2O4 catalyst was synthesized from 2D-layered double hydroxide structure.•The presence of type-II heterojunction system improved OH radical generation.•The half-life of metronidazole removal using ZnO-ZnAl2O4 catalyst reached 100 min.•Catalyst surface OH groups enhanced the adsorption of metronidazole on ZnO-ZnAl2O4.
